+// M5 — Unique index on `repairOrders.roNumber`.
+//
+// The frontend generates RO numbers with Math.random() and now guards against
+// collisions against the loaded set (see src/pages/RepairOrders.tsx,
+// uniqueRONumber()). But two advisors creating ROs in the same second can
+// still race past the frontend check. This migration adds a server-side
+// unique index so the second write fails at the DB layer instead of silently
+// producing two ROs with the same number.
+//
+// If your existing data has duplicate roNumbers, this migration will fail —
+// dedupe in the admin UI first (find records where roNumber = '', set them to
+// unique placeholder values, then retry).
+//
